The Army’s Criminal Investigation Command released figures Friday that show 27 detainees were killed while in U.S. custody between August 2002 and November 2004 in Iraq and Afghanistan.
The deaths are either considered to be homicides or suspected to be homicides.
Once the unit finishes an investigation, it sends the findings to the relevant military command to decide if charges will be filed.
One case involves the death of an Iraqi major general in November of 2003.
Four soldiers based at Fort Carson, Colorado, have been charged with murder and dereliction of duty.
An Army spokesman says every death is taken seriously, and officials are committed to thorough investigations.
